TerraSearch Geophysical of Berlin, Connecticut, carried out a bathymetric Ground Penetrating Radar survey at the Liebman Paleoindian Site in Lebanon, Connecticut.

Using a SIR 4000 paired with a 350 MHz antenna, the team surveyed across Williams Pond to characterize sediment layers and evaluate the site setting of this submerged archaeological location.

This work demonstrates the value of GPR in supporting archaeological research, allowing teams to investigate inundated sites without disturbing sensitive environments.

Happy National Asphalt Day!

From the roads we drive to the infrastructure we rely on every day, asphalt plays a vital role in keeping our world connected. We’re proud to support the asphalt industry with advanced technology that helps uncover inconsistencies during the paving process, such as poor uniformity and significant density variations.

By identifying these issues early, crews can avoid premature failures such as raveling, cracking, and joint deterioration, delivering longer-lasting, higher-quality roads.
Here’s to the people and innovation paving the way forward.

Right Way Drilling and Scanning performed a concrete survey in Miami using a SIR 4000 with a Palm Antenna to locate post tension cables and conduits before core drilling in a high rise building. Thanks to precise GPR data, the team drilled 300 holes with zero problems.
A great reminder of how important accurate scanning is for safe and efficient work on concrete structures.
